To aZZ whom it may concern.-

Be it known thatI, CHARLES WALTER Ron- DELL, a citizen of the United States, residing ful Improvement in Machines for Cleansing and Coating Nails, of which the following is a specification.

The object of this invention is to provide a machine which will serve the double purpose of cleansing the nails after they have been formed in the machine and removing from the nail-points the projections or whiskers, which removal is necessaryin order that the nails may have perfect and well defined points, and the machine of this invention is intended to not only perform the above function but at the same time to prepare and coat the nails with a preservative coating, thereby at one and the same operation completing the nail and coating it under the best conditions.

The invention consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a frontv elevation of the entire device; Fig. 2, an end elevation of the same; Fig. 3, a cross-sectional view of the rotary hopper and shield; Fig. 4, a screen adapted for use with therotary hopper, and Fig. 5 a plate for closing the opening in the hopper.

As shown, the machine is supported upon uprights A, of any suitable construction, secured together by means of rods or bars a and provided at a suitable point with journal boxes B, secured to the front of the supports, and within the j ournal-boxes are hollow trunnionsO, upon one of which is secureda fast and loose pulley-wheel c, and between the uprights of the frame and supported by the trunnions is a rotary hopper D, cylindrical in shape and provided with end walls cl and a hole d in each end leading into the interior of the hollow trunnion. In the curved side wall of the cylinder proper is an elongated hole or opening E, at one end of which is a Socket 6, located on the outer face of the wall, and at the other end of which is a catch or clasp e of any desirable construction, as shown in Fig.1. Over the hole or opening in the hopper, as shown in Fig. 1, is a frame F, one end of which is inserted into the socket extent, the lower eand the other end of which is secured in place by the clasp or catch 6, and within the frame is a screenf, having a mesh of sufficient size to allow the whiskers or waste particles adheringto the nailto fall through after the same have been removed by abrasion from the nails on which they are formed. In order to close the opening entirely when so desired, a closing-plate G is provided of the same dimensions as the frame F, which may be inserted into the socket and secured in place by the clasp in the same manner as the frame F, hitherto described. Located behind the rotary hopper is a guard H, provided with a semicircular wall It and end walls It, the entire guard or protector being of greater di ameter and of greater length than the hopper behind which it is stationed, and said guard or protector is secured to the frame at its ends by means of bolts h or in any other desirable manner. Extending through one end of the guard or protector is a gas-pipe I, located below the hopper and provided with a series of jet-pipes i, which are intended to heat the rotary hopper and the material contained therein. The gas-pipe is provided exterior of the guard or protector with a valve or cook vlfor the purpose of regulating the flow of gas through the pipe. Hinged to the top of the guard or protector by means of a hinge j is a hood J, having a curved outer wall J and end walls 9", the line of curvature of the outer wall being the same as that for the guard or protector, so that when the hood is down, as shown in Fig. 2, the rotary hopper will be inclosed and protected throughout three-fourths of its entire front portion alone being the hood are cut exposed. The end walls of away at their lower corners 7 to allow for the curve of the trunnions. If so desired, a hopper or similar receptacle K may be stationed below the rotary hopper to receive the nails after the same have been discharged therefrom.

V In operation the opening in the rotary hopper is uncovered and a suitable quantityof nails inserted thereinto, after which the opening is closed by means of the frame and screen shown in Fig. 41-, and motion is imparted to the hopper through the hollow trunnions and pulley-wheel located thereon.

The gas-jets are simultaneously lighted, so that as the nails are being rotated within the hopper they will likewise be warmed in preparation for the coating to be applied after the nails have-been thoroughly cleansed by the abrasion incident to their rotation. In order to preserve the heat produced by the gas-jets, the guard or protector and hood are provided, which not only serve to retain the heat but also prevent the abrased waste particles from being thrown out of the machine on all sides, as would otherwise be the case. The hood being movable may be raised and lowered to suit the requirements of the case, so that if the heat becomes too great the hood will allow a certain amount of the heat to escape.

After the nails have been cleansed and heated sufficiently the screen-frame is removed from its socket, and the solid plate (shown in Fig. 5) is inserted into place after the necessary quantity of coating has been inserted into the rotary hopper. The rotation is then continued suflicient-ly to thoroughly coat the nails, the smoke or fumes incident to the coating operation being allowed to escape through the hollow trunnions upon which the hopper is mounted. After the nails have been thoroughly coatedthe catch or clasp may be raised and the plate removed, allowing the nails to fall out of the rotary hopper into the receptacle placed beneath.

It will be seen that the device of this invention is simple in construction and operation and that it enables the coating operation to be performed much more readily and quickly than would be the case if it were necessary to treat the nails to a separate operation after they had been cleansed. Although the device has been described with considerable particularity as to details, it is plain that such details may be considerably modified without departing from the spirit of invention.

It is apparent that difierent kinds of fuel may be used to produce the necessary heat, such as gas, petroleum, or gasolene. In case more heat is required to perform the work the hood can be enlarged, so as to entirely inclose the hopper, if so desired, thus retaining all the heat.

What I regard as new, and desire to secure by Letters Patent, is-

1. In a machine for cleansing and coating nails, the combination of a rotatable hopper having a hole or opening in one of its side walls and provided with hollow trunnions at its ends opening into the hopper, a covering for the hole or opening removably secured thereto, journal-supports within which the trunnions revolve, a guard or protector attached to the journal-supports exterior of the hopper and adapted to partially cover the rotatable hopper and serve to prevent the escape of heat therefrom, and means within the guard or protector for imparting heat to the rotatable hopper, substantially as described.

2. In a machine for cleansing and coating nails, the combination of a cylindrical rotatable hopper having a hole or opening in one of its side walls and provided with hollow trunnions at its ends opening into the hopper, bearing-supports in which the trunnions are mounted, a screen adapted to cover the hole or opening in the hopper, a guard or protector of semicylindrical shape fixedly attached to the journal-supports exterior of the hopper and provided with a hinged hood adapted to project in front of and above the rotatable hopper, a gas-jet within the guard or protector located below the rotatable hopper and adapted to impart heat thereto, a valve exterior of the guard or protector for regulating the gas-supply, and a pulley-wheel on one of the trunnions exterior of the guard or protector for imparting rotation through the trunnion to the hopper, substantially as described.
